com.apple.celestial.plist

I have set the volume limitation on the headphone and headset to 1 (original is 0.826872). I think this is what apple did in the 1.1.1 update. Now you got it for 1.0.2.
Step 1: Jailbreak
Step 2: Use sftp-client (cyberduck) to access your iPhone, go to folder: /private/var/root/Library/Preferences/
Step 3: Make a copy of "com.apple.celestial.plist" as a backup.
Step 4: Put the downloaded file via sftp-client on your iPhone 1.0.2 in folder: /private/var/root/Library/Preferences/
Step 5: Go to Jail again
